Activation energy and temp

Does activation energy change with temperature?

No. Activation energy is the minimum energy required to start a chemical reaction, and since the higher the temperature the more energy present, the more likely the reaction is to reach the activation energy. But the temperature does not change the activation energy.

Activation energy and temperature have a great influence on the rate constant k, but not on each other.

No matter the temperature, a reaction will always have the same activation energy UNLESS the pathway of the reaction is altered using a catalyst. However, k (the rate constant) varies with temperature.
